How do I create a thread in C++ using the standard library?

You can create a thread in C++ using the <thread> header. Here's a simple example:

#include <iostream>
#include <thread>

void threadFunction() {
    std::cout << "Hello from the thread!" << std::endl;
}

int main() {
    std::thread myThread(threadFunction);
    myThread.join(); // Wait for the thread to finish
    return 0;
}

What does myThread.join() do?

The join() function blocks the calling thread until the thread represented by myThread has finished executing. It's essential to ensure that the main thread waits for the new thread to complete.

Can I pass arguments to the thread function?

Yes, you can pass arguments to the thread function using std::bind or lambda functions. Here's an example using a lambda:

int main() {
    int value = 5;
    std::thread myThread([value]() {
        std::cout << "Value from thread: " << value << std::endl;
    });
    myThread.join();
    return 0;
}
